2 Claims. (Cl. 33-180) The present invention relates broadly to masonstools and specifically to a simple and inexpensive tool for positioninganchor bolts in soft mortar in building blocks so that all boltsextending upwardly from the last course of blocks are positioned inalignment and need not be bent to conform to the holes provided for themin the steel or wood beam sills forming the foundations of thestructure.

As now constructed, most frame and steel buildings require anchor boltsthrough the sill beams and each is to be embedded in mortar in one ofthe holes of a building block of the foundation block course. It is thepractice generally to set an anchor bolt in soft mortar and to expectthat the eye and hand could position it in the center of the block andexactly vertical. While this is often possible, frequently the mortarsags enough in the hole to rnisalign the bolt, and the mason, havingmoved on to other tasks and block courses does not find the misalignedor slanting bolt until the mortar or cement has set, necessitatingeither replacing the bolt or bending it to as near a vertical positionas possible, so that the bolt fits easily in the hole in the sill, plateor beam which follows.

The present invention provides a simple and easily constructed toolwhich can hold temporarily at least the bolt upright until initial setof the cement or mortar takes place, and also serves to quickly positionthe bolt at the proper center of the block.

principal object of the present invention, therefore, is to provide asimple tool for setting anchor bolts vertically in cement buildingblocks.

Another object of the present invention is to provide a light weight,easily assembled and constructed tool which will stand an average amountof hard usage as given to masons tools, and is so braced as to noteasily get out of plumb, and one which provides an easily read scale andseries of notches which indicate common widths of building blocks, sothat the mason need only glance at the tool on the block to see that thebolt will be exactly centered therein.

These and other objects and advantages of the present invention will bereadily apparent from the following description when considered with theaccompanying drawings, in which:

Figure l is a view in perspective of a common, cement building blockshowing the present invention thereon holding an anchor bolt.

Figure 2 is a top plan view of the invention.

Figure 3 is a side view in elevation of the invention.

Referring in more detail to the drawing, in which like numerals indicatelike parts throughout the three views, it will be seen that theinvention consists of an upstanding guide member 10 of V-shape, and ahorizontally disposed T-shaped support member 11 secured by themid-point of its cross leg 12 to the lower end 13 of the guide member10. The portion inwardly from the upper end of the guide member 10 isprovided with a scale or rule 14, and the cross leg 12 of the supportmember 11 is marked or engraved with a rule 15, one edge of which isprovided with notches 16 to indicate the common widths 4, 6 and 8 inchesof width of the building blocks commonly in use.

A handle 17 with a convenient hole 13 to hang the tool completes theinvention, and is secured at one end to the longitudinal leg of thesupport member 11 and at the other end to the upper end of theguidernember 10. The handle serves as a brace to keep the guide membervertically disposed relative to the support member, so that it does notget out of alignment and will hold at least temporarily a bolt,indicated at 19, in soft mortar or cement 20 in the hole 21 in abuilding block 22, as seen in Figure 1.

While only preferred embodiments have been here shown and described,other embodiments of the present invention may be made within the scopeof the appended claims without departing from the spirit of theinvention.

What is claimed is:

l. A building block anchor bolt positioning tool comprising anupstanding V-shaped guide member, a horizontally disposed T-shapedsupport member secured by the midpoint of its cross leg to said guidemember at the lower end thereof, said support member being formed on itscross leg with block-width indicating means including a rule and notchesin one edge thereof indicating common widths of blocks, said supportmember being adapted to be supported on the top surface of a buildingblock with said guide member over a hole therein for temporarilycentering between its legs an anchor bolt having its lower end embeddedin soft mortar in the hole.

2. A building block anchor bolt positioning tool comprising anupstanding V-shaped guide member, a horizontally disposed T-shapedsupport member secured by the mid-point of its cross leg to said guidemember at the lower end thereof, said support member being formed on itscross-leg With block-width indicating means including a rule and notchesin one edge thereof indicating common widths of blocks, said supportmember being adapted to be supported on the top surface of a buildingblock with said guide member over a hole therein for temporarilycentering between the legs thereof an anchor bolt having its lower endembedded in mortar in the hole, said guide member being formed at itsupper end with measuring indicia, and a handle connecting thelongitudinal leg of said support member to said guide member at is upperend for vertically positioning said guide member relative to saidsupport member.
